STW20N95K5 N-Channel MOSFET: High-Performance Power Transistor for Demanding Applications
STMicroelectronics' STW20N95K5 N-Channel MOSFET represents the cutting-edge of power transistor technology, combining exceptional electrical performance with robust thermal management. Designed for high-voltage industrial applications, this SuperMESH5™ series component delivers reliable operation in power conversion systems requiring both efficiency and durability.
Advanced SuperMESH5™ Technology for Enhanced Efficiency
At the heart of this device lies STMicroelectronics' proprietary SuperMESH5™ technology, which optimizes the balance between conduction and switching losses. This innovation enables the STW20N95K5 to achieve a remarkable 330mΩ maximum Rds(on) at 9A/10V, significantly reducing power dissipation while maintaining high current handling capabilities. The advanced trench gate structure minimizes gate charge (40nC @ 10V), allowing faster switching transitions in power supply designs.
Engineered for high-voltage environments, this MOSFET features a 950V drain-source breakdown voltage rating that exceeds standard industrial requirements. The device's ±30V gate voltage tolerance provides design flexibility while maintaining reliable operation across varying thermal conditions. With a thermal resistance (RthJC) of just 0.5°C/W, the TO-247-3 package ensures efficient heat dissipation for high-power applications.
